Formerly known as Communist, Catiline is the same great web worker library but with a name you can use with your boss.

A JavaScript library all about workers. Workers should make your life easier not harder and with Catiline launching a new worker is as simple as calling a function, and it works the same across all (modern) browsers.

How easy? var worker = cw(myFunc) creates a worker, send it data with var response = worker.data(YOUR DATA);, response is a promise. It's that easy, for more in depth usage checkout the examples bellow or the API page.

Want to use it? Grab the development version or production version from the dist folder.

For usage in addition to the API page and documentation, I wrote a blog posts about Catiline, or you can browse some demos:

• Parsing a dictionary
• Fractal Map, (April Mozilla Dev Derby Finalist)
• RTree Bounding Boxes
• Census Visualization
• Vector Map Tiles
• Unzipping files and reprojecting maps

Updates and changes are all in the changelog.

There is also a plugin list.

This grew out of my work with earlier versions of this library and my differences in opinion with Parallel.js's direction. There is also a library doing very similar things called operative
